ABSTRACT
The title com-pound, C13H11NO, adopts an E configuration about the C=C double bond. The pyrrole ring is inclined to the phenyl ring at an angle of 44.94â (8)°. In the crystal, mol-ecules are linked by N-Hâ¯O hydrogen bonds, forming ribbons parallel to (020) in zigzag C(7) chains along the a axis. These ribbons are connected via C-Hâ¯π inter-actions, forming a three-dimensional network. No significant π-π inter-actions are observed.
ABSTRACT
In the title compound, C15H14N2O2·H2O, the 1H-pyrrole ring makes a dihedral angle of 59.95â (13)° with the phenyl ring. In the crystal, the mol-ecules are connected by C-Hâ¯O hydrogen bonds into layers parallel to the (020) plane, while two mol-ecules are connected to the water mol-ecule by two N-Hâ¯O hydrogen bonds and one mol-ecule by an O-Hâ¯O hydrogen bond. C-Hâ¯π and π-π inter-actions further link the mol-ecules into chains extending in the [01] direction and stabilize the mol-ecular packing. According to a Hirshfeld surface study, Hâ¯H (49.4%), Câ¯H/Hâ¯C (23.2%) and Oâ¯H/Hâ¯O (20.0%) inter-actions are the most significant contributors to the crystal packing.
